Question

please solve my problem

Answer 1

perimeter area of a square is 4s
as we know that aman takes 5 rounds and he covers 300 m
which is the perimeter is
300/5
which is 60
so the perimeter being 60
side will be :
4s=60
s=60/4 s=15
the area would be
s^2
15^2
which is 225sq.m
the levelling cost is rupees 5
perimeter is 60
cost would be 60*5
which is rupees 300
